In the coordinate plane, A = (4,-1), B = (6,2), and C = (-1,2). There exists a point Q and a constant k such that for any point P, [PA^2 + PB^2 + PC^2 = 3PQ^2 + k.]Find the constant k.

This is urgent, please help me out

Find the equation of the line that goes through the points (4, –1) and (2, –5). use slope formula,equation,to find the slope of a line that passes through the points. m = use slope-intercept form, y = mx + b, to find the y-intercept (b) of the line. b = write the equation in slope-intercept form, y = mx + b.
